Dislikes - anything with artifical sweetner
EXTREMELY ALLERGIC TO:
NutraSweet, Saccharin, Splenda
(hint: if it says Sugar Free, most likely it has one of the above in it.)

Oh and Re-purposing is acceptable. goodness knows that we all have enough to share without breaking the bank during these economically difficult times.

Another tid-bit is you don't have to shop for the entire family/clan... Last year my SS sent gifts to all of us... it was wonderful. I have used all my goodies throughout the year...
